The folks over at Airsplat have reviewed the Double Eagle UMP M89 Laser Scope Airsoft Gun. The gun retails for $154 dollars and looks to be a decent entry-level AEG for players looking to graduate from the plastic variety to full-metal.
From the review:
The gun is a good buy, with the full metal internals and decent performance. Keep in mind that the FPS on the gun is still higher than most CQB arenas may allow. So you may have to down grade the gun, to get to the proper FPS for some fields.
